Modifier Keys; The Keys - Psion Teklogix Workabout Pro Quick Start Manual

2.3.1 Modifier Keys
The <SHIFT>, <CTRL>, <ALT>, <ORANGE> and <BLUE> keys
are modifier keys. Pressing a modifier key changes the function of
the next key pressed. For example, a square bracket is printed
in orange print above the <4> key. Pressing the <ORANGE> key
followed by the <4> key displays a square bracket rather than the
number 4.
The <SHIFT>, <CTRL> and <ALT> keys operate much like a desk-
top keyboard except that they are not chorded – two keys cannot be
held down simultaneously. The modifier key must be pressed first
followed by the key whose function you want modified.
Activating Modifier Keys
When a modifier key is pressed once, the modifier key icon displays the
key in lowercase letters in the taskbar. For example, pressing <CTRL>
once displays ctrl key in the taskbar. Once the next key is pressed, the
modifier key becomes inactive and disappears from the taskbar.
Locking Modifier Keys
When a modifier key is pressed twice, it is 'locked' on. A 'locked'
modifier key icon displays the key in uppercase letters in the taskbar.
For example, pressing the <BLUE> key twice locks it on – it is dis-
played as BLUE KEY in the taskbar at the bottom of the screen.
The locked modifier key remains active until it is pressed a third time
to unlock or turn it off.
